The responsible German body involved in its preparation was the Kommission Reinhaltung der Luft (KRdL) im VDI und DIN (VDI/DIN Air Quality Commission). This European Standard has been
5、prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to support Essential Requirements of EU Directive 94/67/EC of 16 December 1994 on the incineration of hazardous waste. This directive is now replaced by EU Directive 2000/76/EC of 4 December 2000
6、 on the incineration of waste, and this European Standard also supports the Essential Requirements of the new EU Directive 2000/76/EC. In Annex III of EU-Directive 2000/76/EC it is specified that Sampling and analysis of all pollutants including dioxins and furans as well as reference measurement me
7、thods to calibrate automated measurement systems shall be carried out as given by CEN Standards. The revision of this EN between 2001 and 2004 only refers to the normative part. The information given in the informative annexes as examples of operation are kept unchanged, as they represent the state
8、of the art at the time of validation measurements of EN 1948:1996 between 1992 and 1995. The precision and the performance characteristics were determined between 1992 and 1995 in four comparative and validation trials at waste incinerators sponsored by the European Commission, the European Free Tra
9、de Association and the German Federal Environment Agency. Amendments This standard differs from DIN EN 1948-3:1997-05 as follows: a) Extension of the scope: DIN EN 1948 can now also be applied for wide concentration ranges and various emission sources and the described measurement methods are also s
10、uitable for the determination of other low-volatile substances, e.g. of dioxine-like PCBs. b) Inclusion of new terms and definitions, and corrections: The following terms are concerned: field blank, analytical blank, sampling standard, recovery standard, dioxin-like PCBs, isokinetic sampling, limit
11、of detection, limit of quantification, WHO-TEF/WHO-TEQ. c) Addition and correction of requirements for: identification; quantification; quantification of HRGC/HRMS results; calculation of measurement results. d) Inclusion of a new informative Annex B for estimation of the measurement uncertainty.

This directive is now replaced by EU Directive 2000/76/EC of 4 December 2000 on the incineration of waste ii and this European Standard also supports the Essential Requirements of the new EU Directive 2000/76/EC (see a

The precision and the performance characteristics were determined between 1992 and 1995 in four comparative and validation trials at waste incinerators sponsored by the European Commission, the European Free Trade Association and the German Federal Environment Agency. The revision of t
33、his EN between 2001 and 2004 only refers to the normative part. The information given in the informative annexes as examples of operation are kept unchanged, as they represent the state of the art at the time of the validation measurements of EN 1948:1996 between 1992 and 1995. This European Standar
34、d EN 1948:2006 consists of three parts dealing with the determination of the mass concentration of PCDDs and PCDFs in stationary source emissions: Part 1: Sampling of PCDDs/PCDFs; Part 2: Extraction and clean-up of PCDDs/PCDFs; Part 3: Identification and quantification of PCDDs/PCDFs. All three part
35、s are necessary for the performance of the dioxin measurements. In addition for the sampling, extraction and analyses of dioxin-like PCBs the Technical Specification CEN/TS 1948-41is developed and will be transferred to a European Standard after corresponding validation measurements or after an appr
36、oval time of three years respectively. Important changes made in the revision of EN 1948-3: 1.
